db1a93d4fe Change directory permissions in pre-order.
In this order, it won't try to recurse into a directory for which
it doesn't have permission, before changing that permission.
This follows an existing behavior in other BSDs, linux, OS X.

ad34cace15 Standardise chmod, chflags, chown and chgrp recursive symlink processing
chmod, chflags, chgrp, chmod and chown now affect symlinks in -R mode as
defined in symlink(7); previously symlinks were silently ignored.

f0246686c6 - Don't include both <sys/types.h> and <sys/param.h>
- Keep variables sorted

- Fix logic error with -f and -v options - don't print
  the usual -v output if there was an error, whether or not
  we were passed -f

- Don't call free(3) just before exit(2)

- Whitespace fixes

deda5987bc With NFSv4 ACLs, it is possible that applying a mode to an ACL which
is identical to the mode computed from that ACL will modify the ACL.
For example, mode computed from the following ACL is 0600:

   user:kamila:rwx--------C--:------:allow
        owner@:--x-----------:------:deny
        owner@:rw-p---A-W-Co-:------:allow
        group@:rwxp----------:------:deny
        group@:--------------:------:allow
     everyone@:rwxp---A-W-Co-:------:deny
     everyone@:------a-R-c--s:------:allow

However, applying that mode (chmod 0600) changes the ACL into this:

   user:kamila:rwx-----------:------:deny
   user:kamila:rwx--------C--:------:allow
        owner@:--x-----------:------:deny
        owner@:rw-p---A-W-Co-:------:allow
        group@:rwxp----------:------:deny
        group@:--------------:------:allow
     everyone@:rwxp---A-W-Co-:------:deny
     everyone@:------a-R-c--s:------:allow

In chmod(1) utility, there is an optimisation, which makes it not
call chmod(2) if the mode of the file is the same as the new mode.
Disable that optimisation for files which may have NFSv4 ACLs.

5dce647c1b Modernization effort for bin/c*:
o __P has been reoved
  o Old-style K&R declarations have been converted to new C89 style
  o register has been removed
  o prototype for main() has been removed (gcc3 makes it an error)
  o int main(int argc, char *argv[]) is the preferred main definition.
  o Attempt to not break style(9) conformance for declarations more than
    they already are.

01b4e93eff Fixed the bug from the previous revision.
``chown -h owner symlink'' did not set the symlink's owner
if the file the symlink points to already had that owner:

# ls -l alink afile
-rw-r--r--  1 nobody  ru  0 May 31 14:14 afile
lrwxr-xr-x  1 root    ru  5 May 31 14:14 alink -> afile
# ./chown -h -v nobody alink
# ls -l alink afile
-rw-r--r--  1 nobody  ru  0 May 31 14:14 afile
lrwxr-xr-x  1 root    ru  5 May 31 14:14 alink -> afile

Similarly for chgrp(1) and chmod(1).

8e46d9c279 Follow symbolic links named as command line arguments if run without -R.
This is required by symlink(7), ``Commands not traversing a file tree''
subsection, third paragraph:

: It is important to realize that this rule includes commands which may
: optionally traverse file trees, e.g. the command ``chown file'' is
: included in this rule, while the command ``chown -R file'' is not.

For chown(8) and chgrp(1), this is also is compliance with the latest
POSIX 1003.1-200x draft.
